+iS100 - Define Wait Interval Between Wakeup Events
+iSDM - Service Disabling Mode
Default: 0 = The WKUPO_N signal and mechanism is disabled. In
other words, W24 will never assert the WKUPO_N signal.
Result Code:
I/OK If n is within limits.
I/ERROR Otherwise.
AT+iS102? Returns current setting followed by I/OK.
AT+iS102=? Returns the message "0-255" followed by I/OK.
Syntax: AT+iS100=n
Defines the minimal time interval, in milliseconds, that W24
waits before asserting WKUPO_N after de-asserting it. In other
words, W24 will not assert the WKUPO_N signal if the time that
had passed from the previous de-assertion of this signal is not at
least the duration specified by the S100 parameter. This time
interval is required to avoid frequent unnecessary wakeup events
and consequent S102 delays.
The S100 parameter is relevant only if S102>0, which enables the
WKUPO_N signal operation.
Parameters: n=0 .. 255
Default: 0
Result Code:
I/OK If n is within limits.
I/ERROR Otherwise.
AT+iS100? Returns current setting followed by I/OK.
AT+iS100=? Returns the message "0-255" followed by I/OK.
Syntax: AT+iSDM=n
Sets the service disabling mode bits.
Parameters: n=0 .. 7
